Is there a way to customize the default Morlet coefficient ω0 of 6?

The Morlet Wavelet function (see attached image) contains a parameter ω0, the Morlet coefficient, which shifts the balance between frequency resolution and time resolution.
According to the documentation at https://ch.mathworks.com/help/wavelet/ref/cwtft.html, under the Morlet Wavelet function definition (for 'morl', 'morlex', 'morl0), the Morlet coefficient ω0 is set to a default value of 6.
I am trying to replicate a result from a paper for which I need ω0 to be 20. Is there a way to adjust the value of ω0?
I actually need to use the wcoherence function, which makes use of the Morlet Wavelet, so ideally I am looking for a way to adjust ω0 when using wcoherence.

Thanks, I had come across these references before posting here. I am looking for a way to change the Morlet coefficient ω0, not the center frequency and time-decay parameter.
